No information on my mailed return from Feb 2022 1st week

I mailed my return in the first week of Feb 2022. I had to mail it because this time I had to send my wife's ITIN application as well. It's been 5 months now and there's no information at all. "where's my refund" says the entered info is incorrect.

But I know that my mailed returns were received by the IRS because late March I received my wife's ITIN number, using which I mailed my state returns as well.

I got my state returns already last month. But there's still no sign of federal returns.

I'm planning to go out of country for a 3 or 4 months starting from August. I'll be moving out of my current apartment as well.

What should I do in this scenario? If IRS sends me important info, I won't be in the country to receive it.

Please help!!
